SPECIFICATION forming part of Letters Patent No. 477,972, dated June 28,1892.

Application filed May 7 189 1.

To all whom it may concern.-

Be it known that I, FREEMAN M. TEEGUARQ DEN, ofColfax, in the county ofClinton and State of Indiana, have invented certain new and usefulImprovements in Sawing Machines {and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being bad to the accompanying drawings,and to the letters and figures of reference marked thereon, which formpart of this specification.

This invention relates to certain improvements in sawing-machines.

The object of the invention is to provide an improved sawing-machinehaving an automatic feedingdevice capable of feedingplanks or logs ofvarious thicknesses and dimensions to the saw.

A further object is to provide afeedingdevice capable of receiving andfeeding planks, logs, or timber of different dimensions, and which isautomatically varied in speed according to thickness of materialoperated upon; and a further object is to provide cer-v tainimprovements in constructions and details, whereby a greatly improvedand highly efficient machine is produced.

These objects are accomplished by and my invention consists in certainnovel features of construction and in combinations of parts more fullydescribed hereinafter, and particularly pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a perspective of themachine, portions being broken away. Fig. 2 is an elevation fromopposite side to that of Fig. 1, parts being broken away. Fig. 3 is atop plan. Fig. 4 is a horizontal section taken in a plane just abovelower horizontal sills of main and movable feed-frame. Fig. 5 is adetail view of feed-saw and its supporting and adjusting means. Fig. 6is a detail view illustrating the connecting and controlling mechanismbetween the movable feed-frame and the beltshifter.

Referring to the accompanying drawings, a indicates the main frame ofthe machine, comprising suitable vertical posts, end sills Serial No.391,896. (No model.)

c is the saw platform or table. d is a ripsaw extending up therethroughand mounted on horizontal mandrel e in suitable boxes and provided withdrive-pulley) and on outer end with small drive-pulley g. The outerportion of the table, both in front and in rear of the saw, is removablefrom under horizontal supporting-beams 4L 5 6 7, extend-- ing laterallyfrom the main frame so that the saw can be removed from its mandrel. Twoclampingrbars t' 2' are beneath this movable portion of table andpivoted thereto between their ends by vertical bolts 8, so that theclamping-bars 2' 2' can swing beneath and engage lower edges of beams l5 6 7and thereby lock the table down in position. To release the tabie,one end of each clamping-bar should be swung in and the other end out,thereby freeing the bars fromsaid transverse supporting beams; Avertically-movable swinging frame is pivoted within the main frame andconsists of the lower rectangular frame 10, composed-of end and sidesills located within the lower portion of the main frame, so that itsfront end can swing vertirally. A vertical frame is carried by saidlower movable frame and consists of two uprights 9 9, secured to endsills of said movable frame and extending up substantially at rightangles thereto and at their upper ends a suitable distance above saidmain frame connected by upper horizontal beams or frame 50, the frame 10and upright frame 9 and beams 50, carried thereby, swinging togethervertically as one frame. This swinging feed-frame at the lower portionof one end is mounted in suitable-bearings to allow vertical swing ofthe front portion thereof by means of tubes or pipes 11, rigidly securedat their inner ends upon the lower side sills 10.

frame. Alarge pulley 13 is mounted on the outer end of said shaft, andthe driving-belt 14 connects said pulley 13 with pulley g on the rip-sawmandrel. Between the lower side sills of the swinging frame the shaft 12is provided with a cone-pulley 14. Another shaft 15 is journaled in theforward part of the swinging frame only and is provided with thecone-pulley 16, oppositely arranged to cone-pulley 14, the shafts 12 and15 being parallel and belt 17 connecting said two pulleys. Shaft 15 isprovided with a small sprocket-wheel 18at its outer end, connected bydrive-chain 19 with large sprocket-wheel 20, carried by counter-shaft21, journaled on a movable frame and provided with small sprocket-wheel22, connected by sprocketchain 23 with sprocket-wheel 2 L on the end ofthe mandrel 25 of the feed saw or wheel. This mandrel 25 is horizontallycarried by the top beams 50 of the swinging frame, so as to extendhorizontally from the working table and carry the feed saw or. wheel 26in advance of the rip-saw. This feed-saw. mandrel is journaled in anelongated box 27, adjustably clamped to the under sides of horizontalbeams 50 by means of bolts 28, rigid with said box and extending up tothe clamping-block29 upon the upper edges of said beams 50 and throughwhich said bolts pass and are provided with nuts upon the upper. side ofsaid clamping-block;

(See Fig. 5.) By this means the box carrying the feed-saw mandrel can berigidly and adjustably clamped to the movable frame and can be adjustedso that the feed-saw will move toward and from the rip-saw by looseningthe nuts of said clamping-bolts and then moving the box 27 andclamping-block lon: gitudinally of said beams 50, so that the feedsawcan be adjusted to. any desired distance from the rip-saw. Hence whenrip-saws of different diameters are used in the same machine thefeed-saw; can be always kept the desired distance from the rip-saw.Braces 30 are secured to block 29 and to the box 27.

The hub of the feed-wheel is provided with annular groove 31, into whichthe arms of forked piece 32 loosely fit to allow free rotation of saidhub, so that the hub can be moved longitudinally with said forked piece.The horizontal lever 32' is pivoted to the outer end of the forked pieceand fulcrumed at 31' to the feed-saw mandrel-box, the handle of thelever preferably extending toward the front end of the machine. By meansof this lever and by having the feed-saw movable longitudinally on themandrel or having the mandrel and feed-wheel moving longitudinaltogether the feed-wheel can be shifted transversely of the saw-table forvarious purposes. For instance, the operator when wishing to square aninch piece from a piece an inch by an inch and one-eighth moves thefeed-saw to the center of the piece and then moves a suitable gage toone inch, then feeding the piecethrough, sawing off one-eighth-inchedge,

. the proper amountof pressure.

leaving feed-saw in the center of the inch piece and holding it andfeeding it forward, preventing variations.

A suitable gage is provided-such as movable bar 33-ou the saw-table,having rearwardly-extending rack-bars meshing with gearing on shaft 34,which is provided with suitable hand-wheel, suitable clamps being alsoprovided to'hold the gage in proper position. The present invention,however, has no bearing on this gage.-

The front end of the movable feed-frame is counterbalanced by means ofeccentricallymounted vertical wheel or pulley 35, journaled at 35 in thefront-lower portion of the main frame and provided with a strongflexible connection 36, secured at one end to the periphery of saidwheel, so as to lie on its periphery, and at its opposite end secured tothe lower side of the movable front end of said eccentric wheel. Theradial arm 37 is rigid with and extends outwardly from the wheel35 andis weighted at its outer end by weights-such as 3Swhich constantly tendto rotate the eccentric wheel, so as to raise the movable frame,the'weights being of such size and so arranged, that the movable frameis counterbalanced, so as to easily .rise and fall and cause the feed-wheel to en gage wood operated upon with By reason of thisconstruction the feed-wheel is rotatedfrom the saw-mandrel through thecone-pulley,

. ing to aceom modate uneven surfaces or knots in the wood, thecounterbalanced swinging frame always holding the feed-saw against the Iwood, no matter what kind of surface the wood may have or what itsthickness, if not greater than the capacity of the machine.

Any suitable belt-shifting device is provided for belt 17.Preferablyacombined belt shifter and tightener is used, consisting ofthe main frame or body 39, having arms carrying flanged pulleys 40,which rest on the upper length of the belt 17, the frame by reason ofits weight holding the belt tight upon the cone-pulleys. A spool 41 ismounted on one bottom sill of the inner frame opposite said body 39, andthe grooved pulley 42 is mounted on the opposite sill of' the innerframe opposite said spool 41. A cord or connection 43 is Wound on saidspool, passes around said pulley 42, and at its opposite ends is securedto opposite sides of the central portion of said body 39, so that thesaid spool is rotated in opposite directions. The belt-shifter will bethrown toward and from the spool through the medium of the connection 43and pulley 42, thereby shifting the belt on said cone-pulleys andvarying the speed-of rotation of cone-pulley16'and consequently of thefeed-wheel. The belt-shifter slides back and forth on a rigid rod 43.The spool 41 is mounted on shaft 44, extending to the. front 7 end ofthe machine and provided with handwheel 45, whereby the spool 41 can beturned in either direction to operate the belt-shifter to cause thefeed-wheel to rotate fast or slow. The shaft is provided With'joint 44'to allow the shaft to extend upwardly and to swing laterallyindependently of the spool 41 and to allow the feed-frame to swingindepend ently of the upper portion of said shaft. A flanged gear-wheel46 is secured on a shaft 44 and meshes with rack 47, pivoted at itslower end at 45 to upright 9 of the feed-frame, so that its upper endcan swing laterally within yoke 46'. By this means the up-and-down'swing of the feed-frame does not affect the operation of gearing 46 and47, and theflanges of the gearing hold it on the rack. The gear 46 isthrown out of gear with the rack bylifting the upper end of the shaft44out of one notch, holding said gearing in engagement-into anothernotch, which will hold the gears apart, said gearing 46 and 47 being soarranged in connection with the belt-shifter that when the movablefeed-frame swings up to receive a large piece of timber thecontrolling-gearing of the feed-saw is connected to feed slowly and whenthe feed-frame-drops to feed forward a small piece of timber the speedof the feed-saw is proportionately increased. This mode of operating theshaft 44 is not absolutely necessary, as the said shaft can be op eratedby hand-wheel 45. Consequently the gear 46 is longitudinally movable onshaft 44, so that it can be thrown out of gear with rack: bar 47.

The many advantages and automatic action of this machine are obvious andofgreat utility. 7
